本文对线性相位FFT卷积滤波通过六项改革措施
给出了一种改良型运算结构。它不仅消除了复数运算而且使滤波器执行时效率为常规运算结构的2.5~3倍
在一般情况下其性能将超过分裂嵌套式的高速卷积。
The paper presents a new modified type of linearphase FFT convolution filters with six improvements
which can eliminate complex computations and improve performance by a factor of 2.5
3
over the conventional algorithm. In many cases the modified type of FFT convolution filter is generally more efficient than split nesting convolution filter.
